What are the different potential harnessing technologies?
Many different prototypes for wave energy harnessing devices have been developed. While there is huge variety in terms of design and harnessing method, many designs could be described as being a variation of one of the following types: • Attenuators are long multi-segment floating structures placed in parallel to the direction of the waves. As the device is lifted and dropped simultaneously at different points on the structure, this causes expansions and contraction where the segments are connected. This flexing motion can then power hydraulic pumps or other converters which may then power a generator. • Point absorbers operate on the basis of using the bobbing motion of the wave at a fixed point to cause a difference in relative motion of components within, or attached to a floating structure, such as a floating buoy within a fixed cylinder. This stretching and compressing motion can then be used to drive electromechanical or hydraulic energy converters. • Termination wave devices inv
